Abstract

The utility model relates to a resistance-free directional dust-removing household duster, composed of a dust pump body, a motor, a dust pipe, a directional dust-removing pipe, a handle rod, etc. Due to cancelling a common filter bag for a general household duster and adopting an axial dust directional dust-removing technique, dust is removed to specified positions so that the utility model has a completely dust-removing function and has the advantages of low resistance, simple structure, small size, low cost, low power consumption, etc., and in addition, the utility model has simple production process, makes people have no the worry that a dust collecting bag is periodically cleaned and has the function of a room ventilating fan.

Description

The directed dust discharge domestic vacuum cleaners of non-resistance

The utility model is the family expenses cleaner

All domestic vacuum cleaners all are by the filter bag dust removal by filtration at present, and the power of dust catcher mainly is consumed on the filter.Especially along with dust stratification dirt the more, resistance is just big, suction descends, noise also strengthens thereupon.In addition, dust catcher when work still some fine dust see through filter and stay in indoor, can not accomplish complete ash discharge.When dust suction finished, the dust stratification of removing in the bag also was a very thorny job concerning each family.

In view of the existing many disadvantages of existing family expenses deduster, the purpose of this utility model is to design the directed dust discharge domestic vacuum cleaners of a kind of non-resistance, this deduster has been cancelled filter bag, takes directed dust discharge, thereby reaches the purpose of non-resistance, low power consumption, low noise, complete dust discharge.

According to design, the utility model mainly constitutes axial dust suction by sweep-up pipe, filtering grid, the dust suction pump housing, motor, directed dust flue, handlebar etc., radially the directed dust discharge domestic vacuum cleaners of the non-resistance of dust discharge.

Provide most preferred embodiment of the present invention below in conjunction with accompanying drawing.

Accompanying drawing is the directed dust discharge domestic vacuum cleaners of non-resistance profiles.

As shown in the figure, by the dust suction pump housing 1., motor 2., sweep-up pipe 3., directed dust flue 4., 9. handlebar constitute the utility model, wherein the dust suction pump housing have on 1. an axial suction port 5., the side direction dust-exhausting port 6. with impeller 7., 3. sweep-up pipe is connected in axial suction port and 5. goes up, 6. 4. directed dust flue is connected in the side direction dust-exhausting port goes up, and 4. directed dust flue can make dust be discharged to assigned address (for example transom window in room or sewer).Damage impeller 7. in order to prevent the bulky grain foreign material from sucking the pump housing, one deck filter screen is housed 8. at the pump housing in 1., with interception bulky grain foreign material.Filter screen mesh 8. should be not more than 50 orders.

Because the utility model has been cancelled filter bag or other high-drag filter in the existing domestic vacuum cleaners, has eliminated the dedusting resistance.Owing to adopted directed dust discharge can make dust directly be discharged to assigned address, reached the purpose of indoor complete dust discharge on the other hand.

In addition, this deduster volume is little, portable, hangs over the used in air exchange fan that also can do the room in the room.

Implement the present invention,, therefore can reduce the power of motor significantly, save power consumption because resistance reduces greatly.Owing to be directly to discharge dust, not too strict to each position seal request of dust catcher, therefore,, the deduster volume is dwindled significantly on the production technology and all very simple on the pattern, manufacturing cost also reduces significantly.

Claims

1. directed dust discharge domestic vacuum cleaners of a non-resistance, it mainly by the dust suction pump housing 1., motor 2., the 3. directed dust flue of sweep-up pipe 4., 9. handlebar wait and constitute, it is characterized in that an axial suction port being arranged 5. on the said pump housing 1., the side direction dust-exhausting port 6. with impeller 7., 5. 3. its sweep-up pipe is connected in axial dust catcher goes up, and 4. directed dust flue is connected in the side direction dust-exhausting port and 6. goes up.

2. the directed dust discharge domestic vacuum cleaners of a kind of according to claim 1 non-resistance is characterized in that not having filter bag or other high-drag filter, for preventing that the bulky grain foreign material from sucking the pump housing and damaging impeller 7. in 1., are provided with one deck greater than 50 purpose filter screens at the pump housing in 1..
